The sheriff's department would not release information about the suspect, except that the individual they believe is responsible is a juvenile.

An investigation conducted by the San Diego County Sheriff's Department Bomb/Arson Unit, Cal Fire, the San Marcos Fire Department and the Bureau of Alcohol, Tobacco, Firearms and Explosives, has been closed in regards to the May 14 fire.

Investigators did not link the suspect to any of the other destructive California fires from earlier this year.
